In this thesis, the general error sources for psi are analyzed. we find that the relatively low - frequency vibrations at 50hz and lower are the main problem through the analysis of the vibration sources in usual environment. a new vibration compensation method, phase modulating interference fringes fractionizing technology, has been put forward in a creative way
本文分析了干涉測量技術中存在的主要誤差來源,通過對通常環境下振源特性的分析,得到了對干涉測試影響較大的振源的頻率范圍主要在30hz以下,確定了抗振補償的目標和技術指標是使干涉儀的振動頻率50hz ,振幅1 m 。Drawing on a multifunctional internal friction instrument and dma, we tested the damping capacity of all the heat treated samples completely, and then got the damping - frequency spectrum, temperature spectrum and strain amplitude spectrum
然後,在多功能內耗儀和dma上對各熱處理態試樣的阻尼性能進行了全面測試,獲得了內耗頻率譜、溫度譜和振幅效應譜。
